Hi All,

we are using p1020-wlan board with 64MB NOR Flash.

Default root file system partition size for NOR Flash on p1020-wlan board is 27MB, we wanted to increase the root file system partition to 48MB. For this we changed  the Linux Device Tree nor node range and flashed the new device tree on board, but we get the following messages During Kernel Boot up and rootfs partition size has not changed to 48MB.

 

ec000000.nor: Found 1 x16 devices at 0x0 in 16-bit bank
NOR chip too large to fit in mapping. Attempting to cope...
Amd/Fujitsu Extended Query Table at 0x0040
ec000000.nor: CFI does not contain boot bank location. Assuming top.
number of CFI chips: 1
cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness.
Reducing visibility of 65536KiB chip to 32768KiB
RedBoot partition parsing not available
Creating 3 MTD partitions on "ec000000.nor":

mtd: partition "NOR (RO) U-Boot Image" is out of reach -- disabled
ftl_cs: FTL header not found.

 

PLease Guide us how to increase the rootfs partiotn size for NOR Flash on p1020wlan Board.

 

Thanks and Regards,
